Abstract: A hand-pulled instrument, such as an accordion, typically has a sound post (or reed post) on which several reed plates are mounted. The reed plate usually has two oblong openings. Each opening relates to an elongated reed, which is widened at one of its two longitudinal ends for attachment to the reed plate. The opposite long end of the reed is not further fixed. The reed can be made to vibrate in a way that it partially swings into the associated opening. If air flows through the opening, in particular, due to a movement of a bellows of the hand-pulled instrument, such vibration can be generated, and in this way, an audible tone is produced. The reeds are usually attached to the reed plate with a rivet.

Abstract: An electronic keyboard musical instrument includes a storage device, a musical tone generation unit, a resonating sound generation unit, and an adding unit. The musical tone generation unit reads out corresponding musical tone waveform data from the storage device according to key depression information to generate a musical tone waveform signal and a first register resonating sound waveform signal. The resonating sound generation unit receives the musical tone waveform signal to cause the resonating sound generation circuit to generate a second register resonating sound waveform signal according to damper pedal operator manipulation information and the key depression information, and outputs the second register resonating sound waveform signal. The adding unit is configured to add the musical tone waveform signal and the resonating sound waveform signal from the musical tone generation unit and the resonating sound generation unit respectively, and outputting a resulting signal.

Abstract: The invention concerns a method for adjusting the vibration frequency range of a sound producing device with vibrating tongues. The device includes an assembly formed of a comb extended by at least one vibrating tongue, said comb having at least one hole for the securing thereof to a support by means of a support jaw and of a tightening element traversing the support jaw and the hole in the aforecited comb. According to the method, the frequency range is adjusted by reducing the free length of the vibrating tongue or tongues by the localized clamping of said tongues between the support jaw and a local counter-support.

Abstract: A reed guard assembly is provided that may include a mouthpiece and a bracket configured for engaging the mouthpiece. A reed may be held by the bracket against the mouthpiece. A reed guard may also be provided and can be configured for being placed into a guarded position to protect a at least a portion of the reed from damage. The reed guard may be capable of being pivoted with respect to the mouthpiece from the guarded position.

Abstract: A synthetic reed for use in reed-blown wind instruments such as the clarinets, saxophones, oboes and bassoons may be made from an oriented thermoplastic material such as uniaxially oriented polypropylene. The reed may have a profile that is thinner near the tip and in the vamp than the profile of a cane reed of equivalent playing strength, and may be machined from an oriented polymer blank has a higher longitudinal modulus than that of said cane reed of equivalent playing strength.

Abstract: An animal call includes a mouthpiece, a barrel, and a reed. The mouthpiece defines an air channel therein and has a reed bed proximate the air channel. The barrel is coupled to the mouthpiece and has an internal chamber that is fluidically coupled to the air channel of the mouthpiece. A surface comprising the air channel varies in order to maintain a substantially constant cross-sectional area magnitude along a length of the channel. The reed is disposed adjacent the air channel and proximate the reed bed.

Abstract: A game call apparatus is provided which has a mouthpiece including an air inlet, a reed positioned in the mouthpiece and vibrating when air is blown into the mouthpiece, and inner and outer tubular sound chambers mounted on an air outlet end of the mouthpiece. The reed is mounted on an air inlet end of the inner tubular sound chamber, and an air outlet end of the inner tubular sound chamber extends into the outer tubular sound chamber. The outer tubular chamber has an air exit end which tapers radially inwardly toward an air exit. The air exit end includes the air exit which is smaller than an air outlet of the inner tubular chamber. The taper and small exit opening of the outer tubular chamber provides a back pressure to air blown into the mouthpiece which produces a realistic game call sound as the reed vibrates.

Abstract: An apparatus for calling deer, and methods of its use; the apparatus having an adjustable sliding element moved longitudinally by the user to adjust the dimension x of a vibrating reed to vary the sound generated by the deer call. The device includes a barrel assembly with a vibrating reed mounted therein on a reed holder. A metal slider mounted for longitudinal movement within the barrel assembly has a tab extending outwardly therefrom so as to be adjustable without disassembly of the device.

Abstract: An electrically Powered Hand Played Music Box has; a base frame that carries a plurality of 88 damped reed/plectrum tone producing assemblies that can be mechanically accessed in groups of 29 sequenced assemblies each, and placed in correspondence with the keys of a 29 key keyboard so that the player can flexibly select the key that a tune can be played in; an inclined face surface that carries a detachable tune board that carries, according to manufacture, a pre-set or moveable electrical contact for each assembly tone contained in a sequence of tune tones; an electromagnetically propelled switching mechanism that travels a track where it engages remote electrical lines to the tune board contacts and actuates the assemblies that produce the sequenced tones; a tone amplifying microphone, and a speaker; and a key on a single key keyboard that a player taps to actuate the switching mechanism and provide tempo and rhythm to the assembly produced tones.

Abstract: A tubular blowing tube receives a generally cylindrical sounding barrel in one end. A longitudinal notch extending from the inner end of the sounding barrel defines a flat support surface for a pair of reeds. An axial bore opening from the outer end of the sounding barrel merges with a longitudinal axial groove opening to the support surface and terminating short of the inner end of the barrel. The reeds overlie the groove and are retained at the base end of the groove by a cork member compressed between the barrel and blowing tube. The support surface is convex at the inner end where the groove terminates; and the reed tips are bent away from the convex surface and slightly spaced from each other.

Abstract: An audible vibratory biased reed assembly having the properties of being activated or commencing vibration upon being subjected to a predetermined energy level. This assembly utilizes a straight, flat, elongated, closed or clapping reed, to produce a clatter or buzzing sound, with the reed being biased through application of a bias force to one edge to distort its flatness adjacent its free extremity. The bias force is applied by an angular transverse bridge which substantially triples the frequency of the mechanical clatter.
